Measuring Time, Cost, Complexity, Quality, and Security of Ten Free E-Learning Platforms and Their Compliance with Lehman's Eight Laws

E-learning programs in all fields have become necessary, especially after the Covid-19 pandemic, so the use of free e-learning systems has spread and been widely used in many governmental and private institutions, and their provision and management has become an urgent contemporary issue. This paper has selected the top 10 free e-learning programs, and the full code for each program was downloaded and then the code was analyzed using Project Code Metrics, a professional software tool for analyzing and measuring the time, cost, complexity and quality of different parts of the selected programs through source code analysis. After downloading and analyzing 10 programs, the results were analyzed and matched with Lehman's eight laws.
